| Outline of Final Research Achievements |
The purpose of this research is to realize wearable markers that can acquire posture information of human hands moving over a wide area at high speed and use it for immediate information feedback. The main result of this research is the development of a new finger-ring marker consisting of multiple three-dimensional ellipses. The elliptical shape, a parametric curvilinear expression, is reproduced by 3D printing, and we have developed a high-speed image processing algorithm that includes feature extraction and optimization processing in less than 2 milliseconds, and have realized dynamic projection mapping on the palm by cooperating the marker with a low-latency high-speed projector.

人間の手指を入出力に用いる情報機器において，従来技術ではセンシング機器の高速性や装着性に大きな課題があった．特に高速低遅延性と装着持続性の両立は，人間のダイナミクスへの自然な対応・高度な人間機械協調システムに肝要であり，主たる研究成果である楕円群指輪マーカーはその両立戦略を具現化した要素技術である．高速映像投影による即時情報フィードバック系の一例も示したことで，高度な人間機械協調システムへの更なる活用が期待される．
